How do you flirt?

When it comes to flirting I think I do something wrong, or not doing anything at all. Right now Im trying to think what things I do when I flirt but I can't even get my mind clear. I have experience from girls, I had previous relationships ...I dont know, I feel something isn't right at he way I flirt but I can't see what it is. So how do you guys flirt??
